No problem I had a long day myself.
Going by my Moroso power speed calculator it's telling me that 6200 rpm at the stripe with a 28 inch tall tire and 4.10 rear gear puts you at 126 mph, ET in the 10.55 range. A 4.56 gear and 28 inch tall tire puts you at 6400 at the stripe and 118 mph and 11.2 et. I'm by no means an expert but going by what this calculator says you could use some more rear gear. I would skip the NOS for now and put your money into gears and chassis tuning because it sounds like you're closer to the 10's than you think.
